I have considered a simulat shelter/awning. To attach to the TC, my thought was to use 1/4" nylon rope. I think about three or four pieces. one end of each rope would tie to the tarp in the tarp eyes. Probably one on each end, with the others evenly spaced in the middle of the tarp. I would throw each of the ropes over the TC, and tie them to the truck or TC. Depending on thew tarp size, the ropes could be tied to the jacks.
On the loose end of the 1/4" nylon rope, I would attach a tennis ball to each rope. Simply poke a hole throw the ball, insert the rope and tie the ball on. This would make it easier to throw the ball.
On the ground side of the tarp I do as you indicated.
Fact is, I do not remember camping where my EZup was right beside my TC. Seems like there is always some obstacle or exceptionally uneven ground beside the TC. My EZup is water proof.
